Gordon E. Mawdsley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190021682
    Abstract: A system and method for measuring volumetric breast density using a low dose of radiation are provided. This low-dose image can be added to a standard mammographic screening protocol with less than a two percent increase in radiation dose imparted to the subject. This low-dose image can also be used as a single standalone test to determine breast density for younger women for the purposes of risk determination or screening regimen planning. The breast density measurement is more accurate than measurements that can be obtained with existing systems and methods by making use of a compression assembly that maintains a parallel alignment between the compression paddle and breast support table. Additionally, the compression assembly maintains a uniform known thickness of the compressed breast. The system and method have the added benefit that they can be readily implemented on a conventional digital x-ray unit with low cost.

  • Patent number: 9506841
    Abstract: A tissue slicer system that includes a tissue slicing mold capable of producing very thin (e.g., on the order of 3 mm) and uniform slices to be captured from whole, fresh tissue specimens, notably breast lumpectomies, while minimizing distortion. These thin, uniform whole-specimen slices of the fresh surgical specimen increase the area of tissue available for inspection, reduce the amount of tissue lost in trimming during microtomy, and permit tissue processing for producing whole-mount sections.
